Application filed August 26, 1907.

To all whom it may concern:

Be it known that I, ALBERT CHAMPEAU, citizen of the Dominion of Canada, residing at Vancouver, in the Province of British Columbia, Canada, have invented a new and useful Improvement in a Combined Saw Set and Gage, of which the following is a specification.

This invention relates to a combined saw setting anvil and gage, particularly designed for use by loggers in setting the teeth 01' their large cross-cut saws.

Under existing practice, quired to carry two tools to perform this work of setting and gaging the set of saw teeth, an anvil formed of a piece of steel having a forged end and ground face, against which the teeth are struck to set them, and, as a separate tool, what is known as a claw gage, made in the form of a cross having forwardly projecting contact members at the end of each upright and arm of the cross. Three of these contact members, those at the shorter end of the cross, form the contacts of the gage on the face of the saw blade, while the other, at the longer or extended end of the cross, is the contact which gages the amount of set on the teeth. Not only is it inconvenient to have to carry two tools for such purposes, but the weight of the gage is not available as inertia in the anvil. These defects I have overcome in the tool which is the subject of this application, by combining a set gage with an anvil block, furnishing the gage in such a manner that it may be readily applied after the "set of each tooth, and have further made the two central contact members of the gage adjustable to serve various amounts of set, and reversible on the block, so that either end of the block may be used as the anvil face.

The invention is fully described in the following specification reference being made to the drawings by which it is accompanied, in which:

Figure 1 is a perspective view of the device in its position as used as an anvil block, and Fig. 2, a face view showing the reversible cross member of the gage, and in dot and dash lines its position when reversed.

In these drawings, 2 represents a small casting of steel or other suitable material, each end 3 of which is enlarged slightly and ground and beveled to form an anvil face against which the saw teeth may be set. It is furnished with apertures a logger is re- Specification of Letters Patent.

mid-portion, to, afford a convenient hold and facility for handling. From one edge of this block toward each end, contact members 5 and 6 project and, in the middle of the same edge is a recess in which a cross piece 7 is fitted, the ends of which are turned outward from the block and form the other two contact members 8 of the gage. To this cross piece 7 is securely riveted or otherwise secured a screwed stem 10, which passes through the block 2 and is furnished with a milled nut 11 fitting in a recess toward the back, and a milled lock nut 12 on the back. By the nut 11 the cross piece 7 may be advanced or withdrawn in its recess to vary the amount of gage set and may be secured in any desired position by means of the lock nut 12. v

To enable the contact member 5, which determines the set of a tooth to reach from a position on the blade of the saw on which the other contacts bear, below the gullets of the teeth, to the tips of the same, that contact should be a further distance from the cross arm 7 which carries the contacts 8, than is the contact 6 which with 8 forms the seat on the blade of the saw; and this longer reach should be toward that end of the anvil block which is being used to set the teeth, for then the outer end of the block, that is, the one away from the blade, can be simply lowered to bring the gage in contact with the saw blade, instead of it being necessary to turn it round in the hand: Thus, as shown in Fig. 1, the face 9 is the one in use for setting, and to ascertain whether the set is suflicient, the other end of the tool is lowered in the direction of the arrow to bring the gage into use.

In order to enable the other end of the block to be used as an anvil face when one is worn or injured, the cross arm 7 is off-set as shown, from the center of that portion of it which fits the recess: Thus when it is desired to change ends, the cross arm 7 is the position shown in dot and dash lines in- Fig. 2, and

the face 14 becomes the anvil face in use and 5 the gage contact.

I am aware that, prior to my invention, saw setting anvil blocks have been patented having gage members combined therewith, and that such devices have also been atented wherein the gage has been provided with an adjustment; but in no device of this character with which I am acquainted has the cross arm having the middle gage contacts been adjustable or reversible in the block as in mine by which feature I am enabled to use either end of the block as an anvil face Without the necessity of turning the block round in the hand to apply the gage to a tooth just set Having now particularly described my invention and the manner of its use, I hereby declare that What I claim as new and desire to be protected in by Letters Patent, is:

In a saw setting anvil block, the combination with a block, of gage contactmembers projecting from the edge of the block at each end, and a cross piece removably secured in a recess in the middle of the edge length of the block and having at each end other contact members of the gage said cross arm being oil-set from the center of that portion of it which fits the recess of the block so that it may be reversed in the recess to throw the two contact members carried on the cross piece toward one end or the other of the anvil block.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses ALBERT CHAMPEAU.
